freeradius 3.0.21 rlm_sql_freetds problem

[Ali Arslan]

Hello,

I have installed freeradius 3.0.21 on ubuntu 18.04 server. I wanted to use mssql as radius database server, so i installed freetds as
    apt-get install freetds-dev freetds-bin tdsodbc

and configured
    /etc/freetds/freetds.conf file as 
        [RadiusSqlServer]
            host = sqlserver_ip_address
            port = 1433
            tds version = 7.0

and configured /etc/freeradius/mods-available/sql file to use rlm_sql_freetds as deriver.

But I got error: 
    
Could not link driver rlm_sql_freetds: : cannot open shared object file: No such file or directory
Make sure it (and all its dependent libraries!) are in the search path of your system's ld
/etc/freeradius/mods-enabled/sql[27]: Instantiation failed for module "sql" 

Installation of freeradius does not create file /usr/lib/freeradius/rlm_sql_freetds.so.To create this  file  i first install  freeradius 3.0.16 (standard  on ubuntu 18.04) then copy file to another location and uninstall freeradius 3.0.16 and install 3.0.21 and copy file back to/usr/lib/freeradius/  folder.

Is this a bug in freeradius 3.0.21 package?
